Summary

This trial will evaluate the safety and effectiveness of a new treatment for Gaucher disease Type 1 in adults.

Who is the study for?
Adults over 18 with Gaucher Disease Type 1, on stable enzyme or substrate therapy for at least 2 years, can join this gene therapy study. They must have low GCase enzyme activity and agree to use contraception. Excluded are those with recent cancer (except certain skin cancers), past gene therapies, bone diseases not due to Gaucher's, severe liver dysfunction, blood disorders unrelated to Gaucher's, certain infections like HIV/Hepatitis C/CMV, allergies to the treatment components or a history of substance abuse.
What is being tested?
FLT201 is being tested for safety and effectiveness in increasing GCase enzyme levels and reducing symptoms in Gaucher Disease Type 1 patients. This first-in-human trial will also explore how different doses affect these outcomes.
What are the potential side effects?
As FLT201 is a new treatment under investigation, potential side effects include immune reactions such as inflammation or allergy-like responses due to the body recognizing it as foreign; however specific side effects will be monitored throughout the trial.
